. 2 Claims.

This invention relates to an oil container made irom a plasticized elastoplastic film such as a plasticized rubber hydrochloride film. It also includes the plasticized rubber hydrochloride film. The term elastoplastic" is used herein as defined by Fisher on page 941, volume 31, oi Jour nal of Industrial and Engineering Chemistry The oil container of this invention may be constructed in any suitable way. It may be a .stifi container lined with the plasticized elastofiat and sealing the two surfaces of the film at themuth.'

The plasticizers of this invention are oil insoluble and water-insoluble plasticizers. They may be used for plasticizing various oil-insoluble and water-insoluble elastoplastics such as polyvinyl. chloride, polyvinyl chloride-acetate, vinyl chlnride-vinylidene chloride copolymer, polyvinyl butyral, rubber derivatives such as rubber hydrochloride, etc; These plasticized elastoplastics may be used in the form of a lacquer iorcoatms the interior of a container, or they may be used as films not more than .002 of an inch thick irom which a bag may be formed. The bag may be enclosed in a suitable carton.

The simple symmetrical di-esters oi phthalic acid or the group consisting or dimethoxyethyl phthalate, diethouethyl Dhthalate. di-2-chloroethyl phthaiate, dicyclohexyl phthalate, diphenyl phthalate, ditetrahydroiuriuryl phthalate, and

entrant folds has proved satisfactory for paraiiln base lubricating oils. In general, the plasticizers are also suitable for use with napthenic base lubricating oils. Anyone of the following plasticizers may be used: phenyl stearate, phenyl benzoate, glyceryl tribenzoate, beta-naphthyl benzoate, alpha-menthyl benzoate, ethyl-p-hydroxy benzoate, propyl-p-hydroxy benzoate, butyl-phydroxy benzoate. benzyl-p-hydroxy benaoate,

beta-ethoxyethyl-o-benzoyl benzoate, ethoxyethoxyethyl iuroate, phenyl salicylate, beta-naphthyl -ssncyiete. dibenzyl maleate, di (ethoxyethoxydi-o-cresyl phthalate added to rubber ,hydrochloride film increas its impact strength. Although i'or greatest strength the plasticizer should be used in an: amount at least as great as twenty or thirty per cent by weight of the elastoplastic, it is to be understood that smaller amounts may be used where desirable. For instance, rubber hydrochloride film plasticized with thirty per cent by weight of dimethoxyethyl phthaiate made into a bag sealed without re-' ethyl) succinate, di-2-chloro-ethyl sebacate, dicyclohexyl sebacate, di(methoxyethyl) adipate, di(ethoxyethoxyethyl) adipate, di(methoxyethyl) phthalate, di(ethoxyethyl) phthalate, di-2- chloroethyl phthalate, dicyclohexyl phthalate, diphenyl phthalate, ditetrahydroruriuryl phthalate, di-2-chloroethyl hexahydrophthalate, dibenzyl hexahydrophthalate, di-o-cresyl phthalate, methyl phthalyl ethyl glycollate, ethyl phthalyi ethyl glycollate, methyl hexahydrophthalyl ethyl glycoliate, ethyl hexahydrophthalyl ethyl glycollate, tri methyl citrate, triethyl citrate, tri(methoxyethyl) citrate, i-chloro-o-phenyl phenol, pphenyl phenol, o-benzyl phenol, p-benzyl phenol, Santicizer 8 (oand p-toluene ethyl sulionamides).

Divisional applications were filed on July 1,

1943, as follows: Serial No. 493,109 claiming dlethoxyethyl succinate as a plasticizer; Serial No. 493,110 claiming di-2-chloroethyl sebscate and dlcyclohexyl sebacate as plasticizers; Serial No.

493,111 claiming dimethoxyethyl adipate and diethoxyethyl adipate a plasticizers; and Serial No. 493,112 claiming di-2-chloroethyl hexahydro- .phthalate and dibenzyl hexahydrophthalate as plasticizers.

What we claim is: 1. Rubber hydrochloride film plasticiaed Ii about 30 per cent of dimethoxyethyi phthalato to increase its impact strength.

2. An oil package which conslstsof lubricating oil packaged in a bag 0! rubber hydrochloride film plasticlzed with about 30 per cent of dimethoxyethyl phthalate to increase its impact strength, the lubricating oil being in direct con. tact with the film.
